Abstract
The present disclosure provides a method for simultaneously measuring the value of forsterite and trace elements in olivine, comprising the following steps: Step S1: selecting samples, wherein the samples are olivine samples; Step S2: placing the samples in a sample chamber of LA-ICP-MS, and adjusting the position of the samples in the optical axis direction so that the laser beam is well focused; Step S3: optimizing the instrument to make the signal-to-noise ratio of 57Fe be the best; Step S4: adopting LA-ICP-MS peak hopping mode and receiving all the mass peaks of the samples by single electron multiplier (SEM). The present disclosure overcomes the disadvantages of long test cycle and high test cost in the prior art.
